Vulcan C/R Head Gasket GM LSX LH 4.150 x .059

The Vulcan C/R Head Gasket GM LSX LH 4.150 x .059 from SCE GASKETS is purpose-built for serious LS-series engine builders and high-performance mechanics who demand reliability under extreme conditions. This cylinder head gasket is engineered specifically for the driver-side (LH) position in GM LS-family platforms, delivering consistent sealing across repeated heat cycles and combustion loads. Whether you're assembling a street-performance build, a track-focused engine, or a rebuild requiring OEM-equivalent durability, this cut-ring design provides the precision bore matching and compression control that separates professional work from mediocre gasket choices.

At its core, the Vulcan C/R Head Gasket features a steel core laminate construction with a 4.150-inch bore diameter and 0.059-inch compression thickness—specifications critical for maintaining proper squish clearance and ring sealing integrity on LS-series heads and blocks. The cut-ring (C/R) design employs individual metal rings around each cylinder that compress independently, allowing precise bore-to-gasket contact even when cylinder walls, heads, or decks exhibit minor variances common in vintage or heavily modified blocks. This architecture prevents hot-spot leakage at the chamber edge and reduces the risk of coolant or oil seepage around the bore perimeter—failure points that plague lesser gaskets under sustained boost, nitrous, or high-RPM operation.

Mechanics and engine builders working on LS1, LS2, LS3, LSX, and derivative platforms will find this left-hand gasket indispensable for single-sided or complete-engine refreshes where original gaskets have failed or performance upgrades demand superior sealing. Installation requires standard head-bolt torque procedures and correct bolt patterns native to your specific LS block variant; cross-reference your engine family before ordering to ensure left-side fitment. With a shipping weight of 0.83 lbs per gasket, this component is lightweight yet robust enough to handle sustained compression ratios, turbocharged airflow, and multi-season reliability—making it the preferred choice for shops with a reputation to protect.
